As per the survey made, each year more than a million vehicles are stolen in the INDIA (one vehicle every 30 seconds). Vehicle theft occurs not only in metropolitan areas but also it can occur in seedy areas of town. To overcome this limitation, an automotive localization system using GPS and GSM services for the detection of accident location, accident prevention alert and vehicle theft using Arduino Mega 2560 is proposed. The project is designed to find out the exact location of any vehicle, alcohol detection and intimate the position to the concerned authority through an SMS. GSM and GPS technologies are used for that purpose. An alert message is sent to the owner if the driver is drunken alcohol. The owner can send an SMS to stop the engine.

INTRODUCTION Since from the last two decade, due to the high numbers of vehicles on road have increased, traffic hazards and accidents, putting more life at a risk. Every day there is news on road accidents reported in newspapers and on television. Most of the accidents are caused by reckless driving rather than faulty vehicles. Also the amount of vehicle theft is increasing day by day. Each year more than a million vehicles are stolen in the INDIA. GSM and GPS technologies are employed to make vehicle theft almost impossible. Global System of mobile communication is a globally accepted standard for digital cellular communication. Owner of the vehicle uses Subscriber Identity Module (SIM) inserted within his cell phone to send messages to GSM modem which is a part of vehicle theft prevention system that is attached to vehicle. A GSM modem is a specialized type of modem which accepts a SIM card, and operates over a subscription to a mobile operator, just like a mobile phone. From the mobile operator perspective, a GSM modem looks just like a mobile phone GPS technology is used for tracking vehicle. The Global Positioning System (GPS) is a spacebased navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites .The development of satellite communication technology has made it easy to identify the vehicle locations. The proposed system integrates both GSM and GPS technologies. It provides real-time information such as location of user in moving vehicles in a concise and easy-to-read format. Currently GPS vehicle tracking ensures user’s safety while travelling. II. RESEARCH METHODOLOGY The central controller system sends signals to the security system installed in the vehicle that stops or locks the engine immediately. The vehicle is brought to the normal condition upon entering a password. The weakness in [1] is that it relies on the central controller system to take necessary actions in case of theft. The vehicle is not stopped immediately as it takes time for information to pass from owner to central system and then to the security system. There is no confidentiality of password as it is known to the central system which may be misused. In [2], Advanced RISC Machine processor and face recognition system is used as a means of authentication. The owner is notified using MMS with the help of GSM/GPRS when an attempt is made to steal the vehicle. The weakness in [2] is that it uses face recognition for authentication which means only one user will be considered as authorized to drive the vehicle or multiple face recognition system must be used. In [3], IR sensors send message to controller. Car location information is sent to owner. The engine is stopped and doors are locked automatically if the theft is detected. A password has to be entered to unlock the doors and switch on the engine to bring the car to normal condition. The weakness in [3] is that the system uses IR sensors. They are incapable of distinguishing between objects that irradiate similar thermal energy levels. Infrared detectors are also rather expensive, so they are not as widely used as they could be. In [4], password or fingerprint is used for authentication. GSM and GPS are used for notifying the owner and providing location information. Car engine can be turned off if theft is detected. In case of accident, engine is turned off and doors are opened. The weakness in [4] is that the system is vulnerable to password hacking and it uses fingerprint for authentication. This limits the ownership of car to one person.

High security is provided by an alarm system which is triggered when number of incorrect entries exceeds the set limit. Additional security measures include a GSM Module which alerts the owner through SMS in case of a theft attempt. The weakness in [5] is that the system is vulnerable to password hacking. If the thief is able to enter the right password, then, the system fails to prevent vehicle theft. 2.1 Circuit Diagram Circuit Consist of Ultrasonic sensor connected to input pin of microcontroller to sense Distance of coming vehicle and to prevent accidents. Alcohol sensor is to sense amount of alcohol drink by driver. GSM is connected to Send and Receive Messages. GPS is connected to track current location of vehicle. LCD (16x2) is connected to display all the process conducting under microcontroller and to show sensor value. Relay is connected to ARDUINO MEGA microcontroller to switch on and off vehicle using GSM module. Piezoelectric sensor is used to sense accident.

Figure 2.1 Circuit Diagram of Proposed System 2.2 Basic Block Diagram The proposed system design implements microcontroller based vehicle tracking and accident alert system using GSM Module and GPS. Fig. 2.1 shows block diagram of proposed system in which power supply is connected to give 5V supply to microcontroller, LCD and Sensor Module and 12V supply to operate relay, GSM and GPS. GSM module is connected to send and receive message. This system includes a GPS modem which retrieves the location of a vehicle in terms of its longitude and latitude. This data is fed to the microcontroller which is interfaced with a GSM modem. Microcontroller retrieves the location details from the GPS and sends it to the concerned authority in the form of an SMS over GSM modem.

An LCD display is interfaced to the microcontroller for crossing the data received before being sent over GSM. Adopting this technology will be highly useful to transport companies to keep tracking their vehicles and accident prevention.
